WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 380,396, dated April 3,1888.

Application filed May 20, 1885. Serial No. 166,088. (No model.)

To @ZZ whom it may concern:

Beit lrnown that l, Honario J. LooKnART, a citizen of the United States,residing at Fostoria, in the county of Seneca and State of Ohio, haveinvented a new and useful Washing-Machine, of which the following is aspeciheat-ion.

My invention lrelates to improvements in washing-machines in which thematerial to be washed is drawn between revolving rollers, one or more ofwhich has also a longitudinal reciprocating movement to accomplish thenecessary rubbing of the goods. lt also relates to the constructionofthe large roller and to the means for securing the machine in the tub.

The objects of my invention are to provide a simple, durable, andeasy-running machine, to avoid the checking and unequal shrinkage of thelarge roller, and to lessen its weight and to secure a new device forfastening the ma' chine in the tub. I attain these objects by mechanismillustrated in the accompanying drawings, in which- Figure l is a sideelevation of the entire niachine. Fig. 2 is an end elevation; Fig. 3, anend view just inside of the end piece shown as Fig. 2; and Fig. 4 is adetail view illustrating the T-brace and the wedge.

The frame A is made of metal or wood, or both, and is of any suitablesize. It consists of two upright end pieces connected by two flatcrossbars of metal, a a, andthe ilat wooden or metal top piece, a-,allsubstantially as shown. In the end pieces is journaled the large rollerE, one journal of which is extended outside its bearing, and is providedwith a crank, C, for operating the machine.

Above and resting upon the large roller R are two small rollers, S S,which revolve by friction upon the large roller, or upon the goods whichthe large roller may be carrying through. These small rollers are heldin place by the two end pieces, e e, each having two holes in it to forma bearing for one end of each small roller. The rollers are thenjournaled and secured by means of four headed screws or nails driventhrough these bearings into the roller-axis, as shown. The two endpieces, e e, have also each a third hole, as shown in Fig. 3, mid waybetween the roller-bearing holes, through which they are pivotcd on themetal yoke-frame Y. This frameis kept in its place in line with thelarge roller by the arm y, which projects up from the center of theframe into the top piece, a', and by the side ilanges, F, against whichthe ends ofthe frame Y rest.

The small rollers S S are kept pressing down upon the large roller R bymeans of the two iiat steel springs G G, one end of each spring beingsecurely fastened on the under surface of the top piece, a', and theother end securely fastened on the upper surface ofthe frame Y, asshown. -When varying thicknesses of material are passed through themachine, this arrangement allows the small rollers to rise and falLasnecessary,and at the same time keep pressing rmly upon the clothes.

The necessary rubbing of the goods as they pass through the machine isaccomplished by the longitudinal reciprocating movement of the smallrollersS S. This motion is secured by the bevel gear-wheel K on thelarge roller working the smaller gearL, keyed on the verticalcrank-shaft M, which is journaled in the end piece ofthe machine-frame.The crank part of the shaft Mis connected by a pit-manrod, P, to theyoke-frame Y on the arm y,thns imparting the desired movement when thelarge roller is turned. To accommodate this movement, the place in thetop piece, a', is made into a longitudinal slot, and the flanges F arewide enough to confine the ends at all times. rIhe pitman is connectedto the yokeframe at two points, arm y passing through a perforation atp, near the inner end of the pitman, and a projection from saidyoke-frame also passes through another perforation at p', near thecentral portion of the pitman, the lower arm of one of the springs Gbeing also secured upon the same projection. The crankshaft M is formedwith a collar or disk, m, at

the upper end of its crank portiominstead of the usual bend in thecrank-shaft, and this disk prevents the pitnian from binding at thatpoint if it should reach such point in use. The purpose of the ilangesFis also to prevent the clothes from getting over the ends of the rollersR S S, and they are consequently made tostand nearly against thecircumference of said rollers, as shown. They may also be made toconform to the shape of the roliers more IOO closely than is shown inthe drawings, if necessary.. To prevent the material from winding aroundthe large roller, the flat crosspieces a a are placed so that one edgeof each lies lengthwise close to the roller, as shown. The rollers R S Sare ciroumferentially corrugated and made of wood, metal, porcelain, orglass.

In order to fasten the machine into the tub or other receptacle, aT-brace, T, is made, of wood and metal or wholly of metal,and placedwith the stem partlengthwise under thelarge roller R through holes madein the machineframe for that purpose. When in place,anut may be run onthe end which was putthrough to keep the brace T from coming out. Thebrace is now movable lengthwise, and a metal wedge, V-shaped, asrepresented in Figs. l and 2, and as most clearly shown in Fig. 4,sothat it bears equally ou both sides of the crosspiece of the T-braoe andalso against the end of the machine, is used to vary the position ofvthe T- brace, and 'thereby the machine may be firmly clamped in the tubor other receptacle. For tubs of flaring sides the projection X on theend of the machine is also necessary.

I am aware that prior to this invention washing-machines have been madehaving one large revolving roller with two or morelaterally-reciprocating rollers bearing upon it,and Itherefore do notclaim this principle broadly; but

What I do claim as my invention, and desire to secure by Letters Patent,is-

1. The combination of abevel gear-wheel, K, secured to roller R, thesmaller bevel gearwheel,L,meshing with and moved by said gear K, thecrank-shaft M,forming lthe axis of and revolved by the smaller gear, L,the main frame having its cross-barV a provided with a slot,

the yoke-frame having an arm entering said slot, the rollers in saidframe, and the pitman P, all substantially as herein shown anddescribed.

2. The main frame having its crossbar a', provided with a vertical slotelongated in the direction of the length of said bar, the yoke framemovable longitudinally in said frame and having an arm, y, entering thesaid slot in cross-bar a', andthe rollers, all coinbined substantiallyasset forth.

3. The combination of the supportingframe having cross-bar a', providedwith a slot, the yoke-frame Y, having an arm, y, enteringsaid slot, theplates e, pivoted to said frame Y,the rollers S, journaled to saidplates e, the roller R, crank-shaft M, gears K L, pitman P, and springsG G, all arranged and adapted for use substantially as set forth.

4. Thecombination, in a machine substanf tially as described, of asupporting or main frame having an opening forming a way for lthe stemof the T-brace, the T-bracel having its stem movable in said opening,andlthe wedge interposed between the head ot' said brace and the mainframe, substantially as set forth.-

5. The main frame having a projection on one of its ends,the T-bracewith its stem Inov ablelongitudinallyin an aperture in the frame, withits orosspiece projecting from the opposite end of the frame,and thebifurcated wedge interposed between the crosspiece ofthe brace and theframe of the machine, substantially as set forth.
